STREET-CAR INDIGATOR.

Specification of Letters Patent.

' Patented Nov. 11, 1919.

Application filed July 3, 1919. Serial No 308,456.

To all whom it may concern:

Be it known that I, EDWARD MYETTE, a citizen of the United States, residing at Manchester, in the county of Kitsap and State of Washington, have invented new and useful Improvements in Street-Car Indicators, of which the following is a specification.

My invention relates to improvements in street car indicators, to be employed in informing the passengers as to the name of the approaching streets and the like. I

An important object of the invention is to provide a device of the above mentioned character, which is adjustable so that it will operate in opposite directions, and also may be set to operate from any selected street or point.

A further object of the invention is to provide a device of the above mentioned character, which is of simple construction andis reliable in operation.

Other objects and advantages of the invention will be apparent during the course of the following description.

In the accompanying drawings forming a part of this specification, and in which like numerals are employed to designate like parts throughout the same,

Figure 1 1s a side elevation of apparatus.

embodying my invention,

Fig. 2 is a transverse vertical section taken on line 22 of Fig. 1,

Fig. 3 is a perspective view'of a holding pawl support, 7

Fig. 4c is a similar view of an adjustable trip support,

Fig. 5 is a similar View of a latch element for the trip support, and,

Fig. 6 is a perspective View of a pawl controlling member.

In the drawings, wherein for the purpose of illustration is shown a preferred embodiment of my invention, the numeral 10 designates a stationary casing having a front side 11, provided with an opening adapted to be covered by a plate or cover 12, detachably secured in place by any suitable means.

Extending horizontally within the casing 10 are support bars 13, to which are attached journal boxes o'r bearings 14, rotatably receiving a shaft 15. This shaft has a rota table support or disk 16, rigidly secured thereto, as shown at 17. Ali-operating gear:

18 is also rigidly secured to the shaft 15, in 3 advance of the support 16, to rotate the at 21, with a link or links 22, pivoted to cranks 23,'which are fast upon rock shafts 24. These rock shaftsmay be turned by cranks 25. vThecranks 25 may be operated manually by the conductor, or automatically by means set into action by trips arranged near the approach'of the several streets. As a matter of fact, any suitable means may be employed to move the lever 19.

Operating pawls 26 are pivoted upon the lever 19, at 27, and these pawls are moved inwardly to engage the gear 18 by springs 28. A control member or lever 29, is pivoted to the lever 19 at 30, and carries at its inner end a transverse head 31, provided with extensions 32, arranged at a right angle thereto. These extensions are adapted to engage the pawls 26 and hold either pawl out of engagement with the gear wheel 18, these extensions having no engagement with the gear. The control lever 29 is preferably resilient and is provided at its free end with a lock pin 33, to be alternately insert; ed in either of the openings 34:, formed in the lever 19. It is thus apparent that by adjusting the lever 29, the operating lever 19 may be employed to rotate the support 16 in'eithe'r direction.

The numeral 35 designates a control pawl support, provided at its lower ends with feet 36, suitably attached to the beam 13. Control pawls 37 are pivoted to the support 35, at 38, and are adapted to engage with the opposite sides of the gear 18, as shown. These pawls carry arms 39, to be engaged by a shifting element 40, pivoted to the sup port 35, and having a portion l1, to be engaged by a key or the like, for turn ng the same. As shown in Fig. 1, the shiftlngelement 40 is holding the pawl 37 to the right in the inactive position.-

The numeral 42' designates a plurality of indicating elements, preferably in the form of fiat plates 42, having the names of the streets or other data thereon, as shown. These elements are rigidly secured to arms 43, which are pivoted to the carrier or sup port 16, near its periphery, as shown at 44. Each arm 43 is provided with oppositely extending shoulders 45, and an extension 46, arranged between the shoulders, at a right angle thereto. A stop pin 47 is secured to each arm 43, and is adapted to contact with the periphery of the support or carrier 16.

The numeral 48 designates a pivoted trip support, having a hinged joint 49, with a plate 50, secured to a stationary horizontal beam 13. The support 48 carries a pair of spaced trips 52, which are arranged near the periphery of the support or carrier 16, in the path of travel of the shoulders 45 and extension 46 of each arm 43. A latch-lever 53 is pivoted to the support 48, at 54, and is provided with inner and outer openings or notches 55 to receive the end wall of an opening or slot 56, formed in a support 57, attached to the beam 13. The latch-lever 53 extends through an opening 58 to the exterior of the casing 10,- and-is held in the lower position by a pivoted catch 59, adapted to be operated through an opening 60. It is thus seen that the latch-lever 53 may look the trip support 48 in the inner position so that the trips 52 will be in the path of travel of the shoulders 45, or in the outer position, out of this path of travel.

The indicating elements 42 are arranged in close relation and overlap, and when the selected indicating element is visible through the opening 61, it is substantially vertical, while the indicating elements upon the opposite sides thereof are approximately horizontal and move away from the same, whereby it is entirely uncovered.

lVith the pawls 26 and 87 adjusted, as shown in Fig. l, the lever 19 will advance the carrier 16 counterclockwise, in a step by step manner, when such lever is moved in opposite directions for the full extent of its travel. Upon each intermittent movement of the support 16, the lower shoulder 54 of the indicating element 42, such as the element designated Front St, will contact with the trip 52 to the right, thereby turning the arm 43 upon its pivot to assume a vertical position with the extension 46 between the trips 52. The next movement of the support 16 will bring the extension 46 into the contact with the trip 52 to the left, swinging the arm 43 to an approximately horizontal position. It is obvious that a similar operation will occur when the support 16 is advanced in an opposite direction. By reversing the pawls 26 and 37, the lever 19 will advance the support 16 in an opposite direction. Should it be desired to quickly turn the support 16 without tripping the indicating elements 42, the trip support 48 is swung outwardly so that the trips 52 will not engage the shoulders 45. Each pivot 44 is preferably sufficiently stiff so that the indicating element 42 will not fall from the vertical observation position, but the pivot will permit the indicating element turning thereon when it is shifted from this vertical position or approaches the hornzontal. Further, when the element 42 1s 1n the outer or radial position, the extension 46 is located between the trips 52, and the carrier or support 16 is stationary. It is thus seen that these trips will then prevent any considerable swinging movement of the element 42 in either direction, from the display position.

The device is preferably arranged at the forward end of the car, and may be operated manually by the conductor, or automatically set into action by trips or the like, arranged along the track near the approach of the streets.

It is to be understood that the form of my invention herewith shown and described is to be taken as a preferred example of the same, and that various changes in the shape,

size, andarrangement of parts may be re-' sorted to without departing from the spirit of my invention, or the scope of the subjoined claims.

Having described my invention, I claim:
